The Australian Numerals Story

Will this be the most important maths breakthrough since the Indian decimal place value system approximately 1500 years ago or the documentation of zero as a number almost 1400 years ago?

When Australian Numerals and my new number system called podometic arrives in October 2010, (10-10) for a short time YOU can get a launch DVD by just paying the shipping and handling!

I will simply request you make a donation of an amount you choose, direct to a charity of your choice!

Then you'll truly be a part of history by being among the 1st in the world (alongside world leaders) to discover just how simple, powerful and fun, Australian Numerals and podometic can be!

The decimal place value number system was created around the year 499 by an Indian man call Aryabhata*. In the year 628 another Indian called Brahmagupta** wrote the first book to refer to zero as a number.  I honour these men and also Leonard of Pisa or Fibonacci who played an important role by introducing the Hindu-Arabic decimal place-valued system and the use of Arabic numerals into Europe which eventually managed to replace the Roman Numerals number system.  So now, almost 1,400 years later after the rules for zero as a number were documented, it's time for an update. 


As I'm an Australian, I've simply called my work - Australian Numerals and the number system I will be releasing will be called podometic or podo for short.  You see after 25 years I had a flash of inspiration and solved how to simplify our number system!  So why didn't anybody think of this before?  After 25 years of pursuing my crazy quest and lots of reading, experimenting and math homework - just one flash of inspiration! Better late then never!

* His book title 'Aryabhatiya' was translated into Arabic around 820 by Al-Khwarizmi, whose 'On the Calculation with Hindu Numerals' was in turn influential in the adoption of the Hindu Arabic numerals in Europe from the 12th century. Source:

** Brahmagupta's book Brahmaguptasiddhanta is the very first book that mentions zero as a number. Hence Brahmagupta is considered as the man who found zero. He gave rules of using zero with other numbers. Zero plus a positive number is the positive number etc. Brahmagupta made use of an important concept in mathematics, the number zero. The Brahmasphutasiddhanta is the earliest known text to treat zero as a number in its own right, rather than as simply a placeholder digit in representing another number.
